o support for ansistring constants. It's done via a detour because the
JVM only supports UTF-16 string constants (no array of byte or anything
like that): store every ansicharacter in the lower 8 bits of an
UTF-16 constant string, and at run time copy the characters to an
ansistring. The alternative is to generate code that stores every
character separately to an array.
o the base ansistring support is implemented in a class called
AnsistringClass, and an ansistring is simply an instance of this
class under the hood
o the compiler currently does generate nil pointers as empty
ansistrings unlike for unicodestrings, where we always
explicitly generate an empty string. The reason is that
unicodestrings are the same as JLString and hence common
for Java interoperation, while ansistrings are unlikely to
be used in interaction with external Java code

only JVM constructs that are already implemented, but also ones that
will be supported in the future but that aren't implemented yet (to
make it easier to already adapt code to the future changes)

in a single statement, to be added later)
o the unicodestrings are internally simply java.lang.String instances
o at the language level, the unicodestrings are assignment-compatible
with java.lang.String
o constant strings can be implicitly converted to java.lang.String
o since java.lang.String is immutable, in particular changing a
single character in a string is extremely inefficient. This could
be solved by letting unicodestring map to java.lang.StringBuilder,
but that would make integration with plain Java code harder

that's how these operations also work on other architectures
* fixed tjvmaddnode.second_generic_compare() for this new order
git-svn-id: branches/jvmbackend@18338 -
in case of -ar add to the assembler output the height of the
evaluation stack every time it's increased or decreased (to
more easily track missing/wrong inc/decstack() operations)
git-svn-id: branches/jvmbackend@18335 -
u64bit division/mod, and no overflow checking for divisions
(none yet for add nodes either, but that has to be implemented
in hlcgcpu rather than in the add-nodes themselves)
